Including ocean noise in marine spatial planning requires predictions of noise levels on large spatiotemporal scales. Based on a simple sound transmission model and ship track data (Automatic Identification System, AIS), cumulative underwater acoustic energy from shipping was mapped throughout 2008 in the west Canadian Exclusive Economic Zone, showing high noise levels in critical habitats for endangered resident killer whales, exceeding limits of "good conservation status" under the EU Marine Strategy Framework Directive. Error analysis proved that rough calculations of noise occurrence and propagation can form a basis for management processes, because spending resources on unnecessary detail is wasteful and delays remedial action.
在海洋空间规划中纳入海洋噪声需要对大时空尺度的噪声水平进行预测。基于一个简单的声音传播模型和船舶轨迹数据（自动识别系统，AIS），在 2008 年，对整个加拿大西部专属经济区的航运产生的累积水下声能量进行了测绘，结果显示，在濒危居留型虎鲸的关键生境中，噪声水平很高，超过了欧盟海洋战略框架指令规定的“良好保护状态”限值。误差分析证明，对噪声发生和传播的粗略计算可以为管理过程提供基础，因为在不必要的细节上投入资源是浪费的，并且会延迟补救措施。
